Higher-risk groups

Children, older adults, pregnant people, people with heart or respiratory conditions, smokers and outdoor workers may need extra precautions. Seek medical advice if symptoms worsen.

Respirator caution

Malaysia's Ministry of Health notes that an N95 respirator reduces particle exposure when fitted correctly, though it increases breathing effort and is not suitable for young children or pregnant women. People with chronic heart or lung conditions should consult a doctor if uncomfortable.
